## Negative Number Classification

Are negative numbers natural numbers?

- No, because all natural numbers are positive.

Are negative numbers whole numbers?

- No, because all whole numbers are positive or zero.

Are negative numbers integers?

- Yes and no. Some negative numbers (like -5, -13, and -2) are integers. However, some negative numbers (like -27.3, \(-\pi\), and \(-\frac{3}{4}\)) are not integers.

Are negative numbers real numbers?

- Yes, all negative numbers are real numbers

Are negative numbers rational numbers?

- Yes and no. Some negative numbers (like -4, \(-\frac{1}{2}\), and -28.5) are rational numbers. However, some negative numbers (like \(-2\pi\), -e, and \(-\sqrt{7}\)) are not rational.

Are negative numbers irrational?

- Yes and no. Some negative numbers (like \(-2\pi\), -e, and \(-\sqrt{7}\) are irrational numbers. However, some negative numbers (like -4, \(-\frac{1}{2}\), and -28.5\)) are not irrational.

Can negative numbers be prime?

- Sort of. Prime numbers, the way they are usually defined in middle school and high school, are only positive.
- However, in algebraic ring theory, prime numbers are defined in a way that makes two numbers like 7 and -7 essentially the same prime number.

Can negative numbers be even?

- Yes, negative numbers like -2, -4, -6,… are even numbers.

Can negative numbers be odd?

- Yes, negative numbers like -1, -3, -5,… are odd numbers.
